Nice low dose, time release mekatonjn
Verified purchase
Most melatonin is 3 mg which is a pretty high dose. I like this one with 6-hour time release but only 2 mg. This usually keeps me asleep through most of the night.

A good dosage
Verified purchase
I used to take much larger doses of melatonin thinking it would be more effective than small doses. With melatonin, a little goes a long way, and this works well for me.

Great Sleep Support – Source Naturals Melatonin Time-Release Review
Verified purchase
As an Integrative Health Architect and Certified Health & Nutrition Coach, I am always looking for effective, natural solutions for sleep support. The Source Naturals Melatonin Time-Release 2 mg has worked wonderfully for me, providing consistent sleep support throughout the night. After using it for a few weeks, I’m giving it 5/5 stars. However, I do suggest reducing the dosage for those who may be sensitive to melatonin. Quality & Ingredients 🌿 ✔️ Time-Release Formula – The time-release mechanism of this melatonin ensures a slow, consistent release throughout the night, promoting a more restful and uninterrupted sleep. ✔️ Melatonin – The main ingredient, melatonin, is a hormone that helps regulate your sleep-wake cycle and is perfect for supporting natural sleep patterns. ✔️ Safe and Natural – The product is free from artificial colors and preservatives, making it a great option for those looking for a natural sleep aid. Size & Packaging 📦 ✔️ 240 Tablets – With 240 tablets, the bottle provides a generous 8-month supply for a single person taking one tablet per night. This makes it both cost-effective and convenient for long-term use. ✔️ Standard Packaging – The bottle is typical for tablets, keeping the product fresh and secure. Use & Frequency 💧 ✔️ Easy to Take – The tablets are small, easy to swallow, and don’t have an unpleasant aftertaste. ✔️ Serving Size – The recommended serving is 1 tablet before bed, but I suggest starting with half the dose (1 mg) to see how your body responds. I found that half a tablet is more than enough for me, and it helps avoid any morning grogginess. Effectiveness & Benefits ⚡ ✔️ Improved Sleep – The time-release formula helps me stay asleep throughout the night, without waking up too early or having trouble falling back asleep. ✔️ Gentle, No Hangover Effect – I didn’t experience any grogginess or a hangover feeling the next day, making this a gentle sleep aid. ✔️ Regulated Sleep Cycle – I feel more well-rested in the mornings and my sleep cycle has become more regular since I started using this product. Who Would Love This? 💆‍♀️ ✔️ Anyone looking for a natural sleep aid without the side effects of prescription medications. ✔️ People who want a time-release formula for sustained support throughout the night. ✔️ Individuals needing help with jet lag, shift work, or occasional sleep disturbances. Final Verdict – Highly Recommend ⭐⭐⭐⭐⭐ The Source Naturals Melatonin Time-Release 2 mg has been a reliable and effective sleep aid. It helps me sleep through the night without leaving me feeling groggy. I suggest starting with a lower dose (1 mg) to see how your body responds, but I highly recommend it. 5/5 stars!

Amazing
Verified purchase
I deal with insomnia from a chronic illness, I can get to sleep pretty well but find myself waking up around 3 am most nights unable to get back to sleep. Someone suggest time-release melatonin and it's been a game-changer. The pill size is small, so very easy to swallow. You get so many tablets too, such great value. It may seem expensive compared to other brands but this container will last you a long time. Highly recommend if you're a middle-of-the-night waker, this may help you get to 6-7am!

Source Naturals, Melatonin Time Release 2 mg
Verified purchase
This product is in tablet form. Quality is good, bottle and tablets are clean and dry. Natural ingredients used. Size is palatable. and easy to swallow. Dosage of 2 mg is recommended as maintenance dosage by my doctor for insomnia. The benefit is that I get a proper 8 hours of sleep each night. There is no unpleasant taste as it is quite bland and easy to swallow with water.

Decent start dose for melatonin
Verified purchase
This is a great tablet and company to start your melatonin journey. can be taken whole for a timed release or snapped easily for a more instant hit to get you to sleep faster. highly recommended, have been using for over a year, will only use this brand! Also cost is super cheap for the amount of tablets per bottle. I find myself falling asleep very quickly by having a snapped tab and then stay asleep with an unbroken tab.

Best Melatonin around
Verified purchase
Hi, I've been trying many brands of Melatonin over the past 15 years (+ different dosages) This one seems the best to me. Perfect dosage! I'll stick to this one. I tablet at bedtime works fine. I combine it with MethylCobalamin, 1 mg, of the same brand (1 tablet in the morning) : Great !
